Umbilical cord:

  1. The embryo is connected to the placenta through the umbilical cord.
  2. The umbilical cord is a flexible, tube-like structure that connects the fetus to the mother during pregnancy.
  3. The umbilical cord contains three vessels: two arteries, that carry blood from the baby to the placenta, and one vein, which carries blood back to the fetus.

Function of umbilical cord:

  1. The umbilical cord is used as a channel to carry blood between the fetus and the placenta.
  2. The umbilical cord starts to form during the 5th week of conception which connects the placenta to the embryo.
  3. It supplies oxygenated and nutrient-rich blood to the fetus via the umbilical vein and removes carbon dioxide and waste products via the two umbilical arteries.
